Stockhausen's inspiration for Mantra was a tune which 
                  he had been humming, almost in 'free fall' ("I just let my imagination 
                  completely loose") on a long car journey in 1969 in the USA. 
                  A simple figure is repeated many times (there are 26 tracks 
                  on this CD; 887 bars) though with great variety and many different 
                  moods. It was originally intended for two pianists but with 
                  a sound projectionist, whose equipment, it is stipulated, must 
                  be completely inconspicuous to any audience present. Indeed, 
                  the equipment's output for the most part is close in timbre 
                  to that of the piano … finger bells of equal dynamic to 
                  that of the piano around the 320s bars [tr.13] and blocks in 
                  the higher 300s, for instance. 
                    
                  It is the variety and approachability of this simple conception 
                  of Stockhausen that first strikes the listener - whatever your 
                  preconceptions of the composer may be. There are changes in 
                  tempo, length of phrasing, in the relative burden of advancing 
                  the melody (a simple one, to be sure) by the two pianists (Xenia 
                  Pestova, Pascal Meyer) and by Jan Panis (electronics). Not long 
                  into the performance you cannot fail to detect a focus, an enthusiasm 
                  and commitment for the exploration that characterises this work. 
                  
                    
                  Mantra is also a significant piece in Stockhausen's career. 
                  It represents his first fully scored piece for some time. At 
                  the height of his fame, the composer had become more and more 
                  disquieted at the 'debate', let's call it, within his Stockhausen 
                  Group (and indeed between it and himself) over precisely who 
                  was creating the music they performed - so much of what was 
                  actually heard relied either on chance or on (only) a structure 
                  to be elaborated on. Mantra puts an end to that. The 
                  work is also significant in that it represents the start of 
                  what was - effectively - Stockhausen's last compositional phase: 
                  his 'formula' technique. 
                    
                  Its simplicity and concentric nature remind one of some of the 
                  ideas of Feldman; though Mantra seems to have much more 
                  energy. Less energy than Ives, though he's present in Mantra's 
                  pages as well. The fragmentation of Crumb runs through Mantra 
                  too. Some dozen and a half of the 26 groups of bars, which range 
                  in length from 22 seconds to five and a half minutes, have 'titles' 
                  - usually descriptions of how they are to be played … 
                  'Sehr langsam' ('Very slowly'); 'Metallic chords'; 'Stimmen' 
                  ('voices'); 'Gamelan-like' and so on. 
                    
                  These are all characteristics that have a strong theatrical 
                  flavour. So is the entire piece - in conception and execution: 
                  the two pianists face each other engaged in far more than merely 
                  playing the same work. The performance can assume the qualities 
                  of a duel, of intense collaboration, even of a comedic double 
                  act. Neither Xenia Pestova (from New Zealand and Canada) nor 
                  Pascal Meyer (Luxembourg) has other recordings to their credit. 
                  But they approach this interesting music with real flair and 
                  directness. Indeed, precision and concentration are vital if 
                  they are to convey the essence of the repetitions - which they 
                  do from first bar to last. Although the result is of measured 
                  advocacy on their part, it's neither self-conscious not obtrusive. 
                  Their playing is musical first and last. 
                    
                  Panis' role is essential too: he worked extensively with Stockhausen. 
                  And indeed received the composer's approval for the digital 
                  equipment which he had to design once the analogue equipment 
                  necessary to produce the ring modulation was no longer available. 
                  
                    
                  A highly satisfactory and technically, expressively and interpretatively 
                  very pleasing realisation of a key work by Stockhausen, then. 
                  There are others in the current catalogue - that from 1994 by 
                  Yvar Mikhashoff,  Rosalind Bevan and Ole Orsted on New 
                  Albion 25 would probably be the best comparison CD. For 
                  sheer energy and well-directed energy at that, and a controlled 
                  power which truly places our listening experience as close to 
                  the centre of the composer’s conception as any, this latest 
                  Naxos release can be commended. The recording and acoustic are 
                  clean and uncluttered. The booklet contains much useful material 
                  to help understand the context and strengths of what is a really 
                  convincing piece by Stockhausen.
